Experts argue that we need scientific information to solve the complex environmental problems that society faces. However, we know relatively little about when, why, and how scientific knowledge is integrated into the public policy process. My research addresses this gap by examining how various factors affect the way science is applied (or is not applied) to difficult real-world environmental policy problems such as hydraulic fracturing (fracking) or preservation of wetlands. I use a variety of methods to investigate the science-policy divide, including surveys, interviews, social network analysis, and statistical analysis.
- Evaluating how citizens and policymakers learn and make decisions about fracking
- Analyzing how cross-state differences in fracking law and regulation affect the behavior of oil and gas companies
- Understanding adoption and use of wetland assessment tools by state officials
- Assessing the policy impact of cooperative environmental federalism (the manner in which authority over natural resources management is allocated among different levels of government)
- Exploring how norms within large natural resource bureaucracies shape policy implementation
